I'm doing a phd in chemistry http://fittor.fun/karupsow/ myxxxpass Chrysler was doing well with its big 300 sedan, but Ford Motor discontinued its Crown Victoria big sedan and the even-bigger Lincoln Town Car in 2011. GM's Chevrolet brand was working on the next Impala, traditionally a big sedan, but decided to build it atop a stretched version of a mid-size car chassis, while still trying to make it full-size.
